London's Trafalgar Square Christmas tree is traditionally given by NORWAY.
The Trafalgar Square Christmas tree is donated by the City of Oslo in Norway to the people of Britain. This practice began in 1947. It is displayed in the square from the beginning of December until 6th January of the next year.
The Christmas tree is a symbol of thanks from the people of Norway to the people of Britain when British support was given to Norway during the World War II.
A Christmas tree cutting ceremony happens every November in Norway and it is attended by the British Ambassador to Norway, Mayor of Oslo, and Lord Mayor of Westminster. The tree is then shipped to Great Britain and displayed in the Trafalgar Square with traditional Norwegian decor and 500 white lights.
